S2E9. War OR Peace?

You know the saying, "War and Peace go together like birds of a feather". 

Birds have lots of feathers, you see, and a bird would not actually be legally called a bird if it had no feathers... Which is a lot like war and peace when you think about it. I mean, when you really think about it. 

Can you ever truly have peace without having some war? Does war inevitably always lead to peace? Is there a bird that exists in the wild without feathers, and if so, will it declare an unstoppable war?!

We, like the Russian Generals, have absolutely no idea. 

*No birds were harmed (or even mentioned) in this episode.
